WPS has been working with the peregrine falcon nesting efforts since 1996. The program is helping to bring the endangered bird of prey back to Wisconsin.
Pulliam Power Plant
High above the place where the Fox River meets the bay of Green Bay, nestled in the southeast corner of the roof of our J.P. Pulliam Power Plant, you will find the peregrine’s home. There is a specially built box designed for the rare peregrine falcon. This spot has seen the birth of over 55 peregrine chicks. The birds are attracted to power plants because of the tall stacks. Peregrines favor elevated regions for their nests. The birds also like close proximity to open water and a steady food supply. There are a number of other birds in the area that are great food sources for the peregrines.
Weston Power Plant
Since 2006, 20 peregrines have hatched atop our Weston Power Plant. The plant is located in Rothschild, WI.
The peregrine falcon is a crow-sized bird of prey. It is famous and admired for its beauty. It is also known for speed and agility. Native to Wisconsin, peregrines originally nested along high bluffs. The birds chose homes along the Mississippi, St. Croix and Wisconsin rivers. They could also be found in the Door Peninsula.
The population declined due to the use of the chemical pesticide DDT, which weakened peregrine eggshells. The weakened eggshells prevented hatching. As a result, peregrines disappeared from the eastern United States. They were placed on the endangered species list.
The Wisconsin Peregrine Trust works to save these birds. Their goal is to establish 20 nesting pairs. This would allow the population to sustain itself in Wisconsin. The Trust hopes the peregrines can be restored to their natural home.
